In the following sections, each of the primary missions are decomposed into mission planning, management, and replanning segments in order to identify
what the primary functions a human operator will need to perform. The ...

This thesis addresses the uncharted inlet and nacelle design space for low pressure ratio fans for advanced aeroengines. A key feature in low fan pressure ratio (FPR) propulsors with short inlets and nacelles is the increased ...

Neck and back pain is one of the most common musculoskeletal complaints in personnel in variable acceleration environments such as astronauts and military pilots. Ultrasound is known for dynamic imaging and diagnostic ...

Estimating, presenting, and assessing uncertainties are important parts in assessment of a complex system. This thesis focuses on the assessment of uncertainty in the price module and the climate module in the Aviation ...

Engineering systems of the modern day are increasingly complex, often involving numerous components, countless mathematical models, and large, globally-distributed design teams. These features all contribute uncertainty ...

Numerical simulation models that support decision-making and policy-making processes are often complex, involving many disciplines, and long computation times. These models typically have many factors of different character, ...

Extravehicular Activity (EVA) is a critical component of human spaceflight. Working in gas-pressurized space suits, however, causes fatigue, unnecessary energy expenditure, and injury. The problem of injury is particularly ...

New capabilities of Air Traffic Control (ATC) under development in Next Generation Air Transportation system (NextGen) will increase the system capacity to accommodate the expected growth in the air traffic. One of the key ...

In recent years, considerable attention has been paid to hopping as a novel mode of planetary exploration. Hopping vehicles provide advantages over traditional surface exploration vehicles, such as wheeled rovers, by ...

In comparison with conventional and other conceived approaches, hopper spacecraft offer unique advantages in exploring Solar System objects beyond Earth. The present work began with a survey - based on documents from the ...

This month's cover article challenges Air Force leader on the subject of unmanned aerial vehicles. Lt. Col. Lawrence Spinetta and Missy Cummings see disaster, or at least a long-term slide into irrelevance, in recent ...

Potential flow solvers for three dimensional aerodynamic analysis are commonly used in industrial applications. The limitation on the number of discretization elements and the user expertise and effort required to specify ...

Adjoint analysis in computational fluid dynamics (CFD) has been applied to design optimization and mesh adaptation, but due to the relative expense of unsteady analysis these applications have predominantly been for steady ...
